DETAILED DESCRIPTION

Embodiments of the present disclosure include apparatuses and methods for a stacked lighting emitting diode (LED) display. A stacked LED display can include a first array of LEDs that are configured to emit red light, a second array of LEDs that are configured to emit green light, and a third array of LEDs that are configured to emit blue light. The first, second, third arrays of LEDs can be configured to emit an RBG image. A pixel of the stacked LED display can comprise an LED from the first array, an LED from the second array, and an LED from the third array that are in a common row and column position of their respective array. For example, a pixel can be comprised of an LED in the first column and eight row of the first array, an LED in the first column and eight row of the second array, and an LED in the first column and eight row of the third array.

In a number of embodiments, the stacked LED display can include a number of actuators configured to adjust a position of a first array of LEDs in an first direction (e.g. x direction) and a second direction orthogonal to the first direction (e.g., y direction), adjust a position of a second array of LEDs in the first direction and the second direction, and adjust a position of a third array of LEDs in the first direction and the second direction. The actuators can be configured to adjust the position of the arrays of LEDs and/or each LED in the first direction and second direction to control a packing scheme of the pixels of the display. A packing scheme can refer to the position of the LEDs of a pixel relative to each other in the first direction and second direction. For example, a pixel comprising a red LED, a green LED, and a blue LED can have a packing scheme where the LEDs completely overlap each other, partially overlap each other, and/or do not overlap each other.

In a number of embodiments, each of the LEDs in the stack of LED arrays can be individually controlled, activated, and deactivated. The LEDs can be individually controlled, activated, and deactivated to control power consumption of the device and/or control the intensity of the light emitted from each of the LEDs.

As used herein, designators such as “N,” “M,” etc., particularly with respect to reference numerals in the drawings, indicate that a number of the particular feature so designation can be included. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” can include both singular and plural referents, unless the context clearly dictates otherwise. In addition, “a number of,” “at least one,” and “one or more” (e.g., a number of memory devices) can refer to one or more memory devices, whereas a “plurality of” is intended to refer to more than one of such things. Furthermore, the words “can” and “may” are used throughout this application in a permissive sense (i.e., having the potential to, being able to), not in a mandatory sense (i.e., must). The term “include,” and derivations thereof, means “including, but not limited to.” The terms “coupled,” and “coupling” mean to be directly or indirectly connected physically or for access to and movement (transmission) of commands and/or data, as appropriate to the context. The terms “data” and “data values” are used interchangeably herein and can have the same meaning, as appropriate to the context.

The figures herein follow a numbering convention in which the first digit or digits correspond to the figure number and the remaining digits identify an element or component in the figure. Similar elements or components between different figures can be identified by the use of similar digits. For example, 104 can reference element “04” in FIG. 1 , and a similar element can be referenced as 204 in FIG. 2 . As will be appreciated, elements shown in the various embodiments herein can be added, exchanged, and/or eliminated so as to provide a number of additional embodiments of the present disclosure. In addition, the proportion and/or the relative scale of the elements provided in the figures are intended to illustrate certain embodiments of the present disclosure and should not be taken in a limiting sense.

First array 104-1, second array 104-2, and third array 104-3 can be configured in a stack and can be parallel to each other. For example, array 104-3 can be on top of array 104-2 and array 104-2 can be on top of array 104-1.

First array 104-1, second array 104-2, and third array 104-3 can be micro-LED arrays, where each micro-LED can be controlled and provides light for a pixel of display 100. First array 104-1 can be configured to emit red light, second array 104-2 can be configured to emit green light, and third array 104-3 can be configured to emit blue light, such that display 100 produces an image in a red green blue (RGB) format. In a number of embodiments, signals can be provided to the first array of LEDs 104-1, the second array of LEDs 104-2, and the third array of LEDs 104-3 such that display 100 produces an image in a YCbCr format.

The display 100 may be a television display, a computer monitor display, and/or a touchscreen display of a mobile device, such as a smartphone, for example. The controller 110 can be communicatively coupled to the LED arrays 104-1, 104-2, and 104-3 of display 100. As used herein, “communicatively coupled” can include coupled via various wired and/or wireless connections between devices such that data can be transferred in various directions between the devices.
